I have a failed install of Exchange 2013 SP1 in my domain. We already have a production Exchange 2007 Server in the same domain. How can I remove Exchange 2013 manually (ADSIEDIT) without affecting Exchange 2007? Especially want to get rid of databases from the old install(s). I am running this off of a VM so I can just spin up an old snapshot to get rid of Exchange on that machine.
